Please, do NOT force your toddler to hold the pencil the way a school child does, with 3 fingers on the pencil â you may do more harm than good. It is very hard to âunlearnâ a poor pencil grip later in life! Each stage of holding a pencil or crayon is dependent on how âsteadyâ the shoulder and arm muscles are.
In the equation of a straight line (when the equation is written as  y = mx + b ), the slope is the number  m  that is multiplied on the x, and  b  is the y-intercept, where the line crosses the y-axis.
Calculate the slope (which is called m) using your two points. The slope is the distance the line rises for every unit that it runs (or moves to the right). Subtract the y-coordinate (second number) of the second point from the y-coordinate of the first point.
